i RESILIENT WHEEL.

Application sied April as,

To all whom 'it may concern.' y

Be it known `that I, DONALD STEWART KENNEDY, a citizenof the United States, and a resident of the city of New York, borough of the Bronx, in the county ofBronX and State of New York, have invented a new and Improved Resilient Wheel, of which the following is a description My invention relates to resilient wheels l0 and more rparticularly to the wheels of motor vehicles. i y y y i f The general objectl of my invention is to provide an improved wheel of the indicated type eiiicient in affording resiliency while possessing the maximum stability, and lto provide a wheel wherein the deformation of 'the resilient elements at a given point under an imposed load or due to shock, `will be widely distributc-id circumferentially of the wheel. a a

lThe nature of the invention and its advantages and distinctive features will clearly `appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a partici this specification, it being understood that the drawings are merely illustrative of practical examples ot the invention.

Figure 1 is apartly sectionalside elevation of the greater portion of a wheel embodying my invention;

Figure 2 is an enlarged transverse section on the line 2--2, Figure 1; y

Figure 3 is an enlarged detail view of a portion of the wheel shown partly in side elevation and partly in section, taken in the plane of the wheel; y Figure 4 is aview similar to Figure y3 but illustrating a modied arrangement of 40 parts.

Referring at first more particularly yto Figures 1 to 3, the letter A indicates portions of a wheel which may be of any approved form, B indicating the Jtelly; C, the usual fixed rim thereon of known form, and D and E the lugs and their securing bolts', all of which may be of any approved construction. 4 i

'1n accordance with my invention I provide an inner rigid rim 10 of unbroken continuity and advantageously slightly dished Q or channeled adapted to be heldfby the lugs A.D and the flange of the ixedrim C, or

other suitable means to demountably secure said rim 10. Between the inner and outer rims l provide interposed resilient means including an annular resilient float- ,ing element 13 sustained tor iiexure radially inward or radially outward at all points about said element through the medium of bowed springs 15 interposed between an inner band 11 and the adjacent annular floating element and additional annular series of bowed springs 15 outside of said floating n element,

1n the form shown in Figures 1 to El the outer annular series of bowed spring meinbers 15a aresecuredto the floating element 13 and at points remote from the connection with said floating element,`said spring `members being connected with an outer `also pass through said" outer rim 12 and said band 141. The sinuous element 'forming the spring members 15 is bowed alternately toward the inner annular band 11 and toward Vthe floating element 18 and the bows or spring members are secured alternately to said element 13"and` to the band 11 at points remote Jfrom each other by rivets 19, 20. Similarly, the sinuous element forming spring members 15a is bowed alternately toward the floating element 18 and toward the outer band 14e, the bows or spring members 15a being secured alternately to said i'loating element 13 and band 14 at points remote Jrorn each other by rivets 21, 22 or by brazing or other suitable means.

ln Figure 4 the inner and outer bands 11 and `14e are omitted.` rEhe outer springs 15b i corresponding with springs15- are secured to the heating element 13 byrivets 21a and directly to the tire riin'12a corresponding with rim 12 by riVetS 22a, l`lie'pinneil'l springs Cfr illustrated Ved to be mounted-on a i 15C corresponding with springs 15 are secured by the described rivets il() to the 'floating eleinent 13 and they are secured directly to the rini 10 by rivets 1G parsingv 'through blocks 16C between said springs 15 and said riin 10.

illy the use oit theA floating annular resilient element between the inner and outer rinis and the sinuous elements oriningr both bowed springs at the inside andoutside oit the "ioating elenient7 a depression of the outer rim is effective through the rband ll'on the, bowed springs V15n and floatinggeleinent 13 and troni thelttcr to the spring ineinliiers 1,5. By the provision oi the sinuous eleinents 157 llL and the floating` annular elenient 13, the deformation and stressesv are distributed annularly of the Wheel through the boris oi the sinuous elements and the floating annular element tor essentially one-halt thejrheel instead of being localized by exerting the ,de-

pressinfr torce through resilient elements alinost directly to the inner rirn of the Wheel.

Separate tread blocks QS are employed in practice on -the rini 12, 011122 to constitute a cushion tire. Said tire-receiving rim 12 (or 123') is resilient. On said rim at the sides are series 'ot separate iianges 2d at each side the separation olf the flange members permitting ilenure of the riin. @n said riin also are produced at intervals larger :flanges Q5 through which bolts Qtlpass. saidbolts pass ing` also through clamp blocks FZ7 preferably et" inetal and preferably of elliptical or oblong torni to present a broad bearing` surface Which clainps ianges 28 formed on adjacent separate tread blocls 23 at the bases ofthe tread blocks. vForined in the tace of the blocks 23 inay be cup-lilre depressions 29 yto give adhesion and prevent slridding and to inalre bloclts more yielding.

I Would state in conclusion that Wliiletlie examples constitute practical einbodinients of niy invention, I do not liinit iryseli2 strictly to the `mechanical details herein illustrated,` since manifestly the saine can be*considerably` varied without departure troni the Spirit ot theinvention as deiinedin the appended claiins. ,i l
